Finest diabas - granite. Free of faults. No deflection and high torsional rigidity. From a length of 750 mm onwards, the beams have handles at the front faces.

Also available as a lightweight construction.

Accuracy
2-sides precise. The 2 narrow longitudinal faces are flat and parallel within the indicated JFA precision grade finest ground and lapped.

JFA precision grade I+

JFA precision grade I++

JFA precision grade LAB

Test certificate / Calibration
A test certificate is part of scope of delivery. Measuring results are retraceable to National standards. On demand, a factory calibration certificate or a DAkkS calibration certificate will included in the delivery.
